Triangle is among the eastern Prince William County communities that Prince William Water supplies from the Occoquan Reservoir, so the typical home here has no well pump. Most of the housing is newer, and pressure problems usually come from a regulator or the line into the house. For pump equipment or a pressure drop, call the number on this page to be connected with a local plumber in Triangle.
Local conditions in Triangle
Triangle sits between Dumfries, Prince William Forest Park and Marine Corps Base Quantico, home to the National Museum of the Marine Corps. Prince William Water names Triangle among the eastern county communities it supplies with Occoquan Reservoir water treated at Fairfax Water's Griffith plant. Virginia American Water runs a separate system in another part of the county, so if you are unsure, the name on your bill settles it.
The median home in Triangle was built around 1999, so most houses connected to public water from the start. Pressure regulators installed then are now old enough to start sticking. Prince William Water describes its water as moderately hard, so deposits are a modest factor rather than a major one. Pump equipment here is mostly sump pumps in basements and the occasional irrigation or booster pump. Those share switches, check valves and floats with well systems, and they fail in similar ways, so the same plumber can test them. A pump that hums without moving water, or one that runs when nothing should be calling for it, is worth a look before the next storm.
| Option | Best when |
|---|---|
| Replace the pressure regulator | Low or surging pressure throughout a house on public water |
| Repair the owner's water line | Wet ground or a meter that moves with all taps closed |
| Replace a switch, float or check valve | The pump motor is healthy but the controls are not |
| Replace the pump | The motor overheats, trips the breaker or cannot move water |
Signs to watch
- A meter dial that turns when nothing is running
- Pressure that drops when the irrigation comes on
- A sump pump that runs often during dry weather
- Noisy pipes after a quick faucet shutoff
Timing and seasonal notes
Heavy summer storms put sump pumps to the test, and many fail in the first big rain after months of sitting idle. In winter, protect any pump or line in an unheated space. For main breaks or outages, Prince William Water's emergency dispatch is 703-335-7990, and permits for plumbing work in Triangle come from Prince William County's Building Development Division. If you suspect the regulator, a plumber can confirm it in minutes with a gauge on an outside spigot, which is usually the first step on any Triangle pressure call.
